Development of a prototype photogrammetry-based form measurement system for additive manufacturing applications
Funding: University of Nottingham Hermes
Duration: March 2019 – November 2019
Team: Samanta Piano, Mohammed Isa, Danny Sims-Waterhouse
Partners: Xaar 3D
The research within MMT has developed a camera-based photogrammetry system capable of addressing additive manufacturing (AM) applications. By acquiring multiple 2D images, the system software reconstructs a 3D point cloud which represents the component’s surface geometry. The current prototype software performs the calibration, set-up, data capture and post-processing tasks relatively slowly – further work is required to deliver process cycle times to industrial requirements.
This project will deliver system control software, and will seek to incorporate the principles of information-rich metrology (IRM), developed within MMT. IRM features artificial intelligence (AI) and CAD model recognition (as well as other a priori data), allowing the system performance to be optimised by determining camera and object orientation, accelerating feature-matching, and positioning the cameras during data capture.
